Answer:
Braille materials or auditory software
Step-by-step explanation:
For visual impairments up to the focus of 20/200, a person sees a blurr image. For vision problems upto such levels tools such as auditory software and large-font presentations can help a student in understanding the medical terminologies.
But in case the impairment is higher than this and a student is unable to visualize even partially then Braille materials must be used.
